Take note that Mario will be fighting alone in this battle. Make sure to give him the best equipment before the fight!

It is recommended to defeat Rematch Johnny as quick as you can since each of his attacks can still be devastating without perfect blocks. You can try out the Lazy Shell Armor for reducing damage at the cost reduced damage that you deal.

Remember that you cannot recover your HP and use items in this fight, so choosing higher attack or higher defense is a matter of whether you can endure Johnny and if you need more time to make or correct battle decisions.

Best Equipment for Each Character

How to Beat Johnny Rematch and Strategy

Equip the Quartz Charm from Culex Purely a One-on-One Duel Set Your Active Party for Ally Buffs Use Normal Attacks on Rematch Johnny Practice Block Timing You Cannot Use Items

Equip the Quartz Charm from Culex

Accessories	Effect
Quartz Charm	・Prevents instant death, halves enemy attack damage received, and adds 50% damage to attacks performed.

It is best that you have the best equipment available for Mario. Obtaining and equipping the Quartz Charm is highly recommended since it gives you access to buffs that you normally cannot have without other support buffs (like Geno's Geno Boost).

This will make the fight less demanding in terms of using Action Commands, since you will have to rely on well-timed blocks to survive.

Best Accessories

Can Mitigate Lazy Shell Armor Debuffs

Left: Hero Shirt, Right: Lazy Shell Armor. Tested at Lv. 29 with Balanced Build.

Equipping the Quartz Charm will also mitigate the debuffs given by the Lazy Shell Armor (which increases your defense tremendously) when it is equipped. At Lv. 29, with a Mario Balanced Build, you should be able to take around 5 direct hits from Skewers, compared to the Hero Shirt which will put you at risk of 2-3 direct hits depending on Mario's health (around 190+ at that level).

The Lazy Shell Armor will also help reduce damage from special attacks like Fire Saber and Diamond Saw to 1 damage on block.

This can make it more comfortable in dealing with Rematch Johnny at higher levels, enabling you to receive more punishment from his damaging Skewers and giving you more chances for a come back if you make mistakes. If you can hold on to the fight with good but not consistent perfect blocks, the Lazy Shell Armor is an ideal alternative to use.

Purely a One-on-One Duel

Unlike his fight alongside his Bandana Blues in the main story, this post-game boss battle with him is purely a one-on-one duel. This is the ultimate test in knowing Mario's and Johnny's moves.

Make sure to have the best equipment ready before taking this fight. If needed, switch out equipment with other party members! It would be good also to grind levels if you want to make the fight more convenient.

Set Your Active Party for Ally Buffs

Your active party in this boss battle will not be fighting alongside you. Instead, they will be on the sidelines cheering for you and providing you their passive Ally Buffs.

It is recommended to have Geno for a boost in Attack and Speed, and Peach for Magic Defense in the active party slot.

Use Normal Attacks on Rematch Johnny

Rematch Johnny is resistant to specials, so it best you focus on dealing damage to him with normal attacks! Time Mario's attacks as much as you to consistently deal extra damage.

Practice Block Timing

Since this battle is a one-on-one with Johnny, making sure you can survive his attacks is extremely important!

Johnny's Skewer this time around can be particularly devastating since it can cause enough damage for a 1-hit KO. Make to block this one, especially when he is buffed with Get Tough.

Make sure to time your blocks to reduce damage receive. If needed, heal yourself with Max Mushrooms!

You Cannot Use Items

During the fight against Rematch Johnny, the Item button will be faded out, meaning that you will be unable to use any items.

This locks you out in any recovery items for the fight. Make sure that you have replenished your HP prior to duelling with Johnny.

Johnny Rematch Attacks

Rematch Johnny Attacks

Normal Attack

Rematch Johnny will pull back the trident in his hand to perform a stab. To time a block on this, it is best press right as he extends the weapon with his hand.

Skewer

Rematch Johnny's signature Skewer is the more damaging for of his regular attack, signalled by the rotating tip. To block this, time your button press right as the trident extends.

Take note that he will not do a pull animation on this one (instead he will lower and position his weapon.)

Diamond Saw

Two crystal snowflakes will be launched right behind Mario in a movement similar to a boomerang.

You will want to wait momentarily and listen in as the snowflakes get closer from behind, then time your button press.

Fire Saber

Time your button press just right after he shakes the sword for the third time (it will look the slowest compared to his first two sword shakes).

Vigor Up

Vigor Up is used to increased its user's attack power, so Duel-Ready Johnny's attacks will hit harder.

Make sure to practice your Action Command blocks well since doing perfect blocks to reduce your damage to the minimum will help!

Get Tough

Get Tough increases its user's defense power, and will be used by Duel-Ready Johnny when his HP is low enough. This signals the second-half of the battle.
